Are there atoms in the constitution of things? Or is everything made of atomless ‘gunk’ whose proper parts have proper parts? Anaxagoras is the first gunk lover in the history of metaphysics. For him gunk is not only a theoretical possibility that cannot be ruled out in principle. Rather, it is a view that follows cogently from his metaphysical analysis of the physical world of our experience. What is distinctive about Anaxagoras’s take on gunk is not only what motives the view, but also the particular type of gunk that he develops. It is qualitative gunk, rather than material gunk. Anaxagoras’s ontology was developed before matter was ‘invented’. It includes quality tropes only; they are gunky. The resulting metaphysical view – a world of qualitative gunk – is new, in the sense of being hitherto unexplored; and yet, it is derived from Anaxagoras’s writings. Drawing on Anaxagoras’s insights, this paper offers a sketch of what qualitative gunk ontology l..

In everyday life we assume substantial behavioural reliability in others, and on the basis of it we talk of people as acting “in character” and “out of character”. This common assumption seems intuitively well founded. But recent experiments in social psychology have generated philosophical controversy around it. In the context of this debate, John Doris challenges Aristotle’s well known and influential view that people’s behavioural reliability with respect to acting virtuously is underpinned by character traits, understood as settled and integrated dispositions of the agent to have appropriate judgment and appropriate feelings toward what she is called upon to do in a given situation. In this paper I will take John Doris’ challenge at face value, and argue in response that Aristotle’s position is not undermined by it. In fact, rethinking Aristotle’s realism about character and moral virtues in light of Doris’ criticism has important and hitherto unexplored heuristic value for Aristotelian scholars and situationist philosophers alike.

Is power the essence of divinity, or are divine powers distinct from divine essence? Are they divine hypostases or are they divine attributes? Are powers such as omnipotence, omniscience, etc. modes of divine activity? How do they manifest? In which way can we apprehend them? Is there a multiplicity of gods whose powers fill the cosmos or is there only one God from whom all power(s) derive(s) and whose power(s) permeate(s) everything? These are questions that become central to philosophical and theological debates in Late Antiquity (roughly corresponding to the period 2nd to the 6th centuries). On the one hand, the Pagan Neoplatonic thinkers of this era postulate a complex hierarchy of gods, whose powers express the unlimited power of the ineffable One. On the other hand, Christians proclaim the existence of only one God, one divine power or one 'Lord of all powers'. Divided into two main sections, the first part of Divine Powers in Late Antiquity examines aspects of the notion of divine power as developed by the four major figures of Neoplatonism: Plotinus (c. 204-270), Porphyry (c. 234-305), Iamblichus (c.245-325), and Proclus (412-485). It focuses on an aspect of the notion of divine power that has been so far relatively neglected in the literature. Part two investigates the notion of divine power in early Christian authors, from the New Testament to the Alexandrian school (Clement of Alexandria, Origen, Athanasius the Great) and, further, to the Cappadocian Fathers (Basil the Great, Gregory of Nyssa), as well as in some of these authors' sources (the Septuagint, Philo of Alexandria). The traditional view tends to overlook the fact that the Bible, particularly the New Testament, was at least as important as Platonic philosophical texts in the shaping of the early Christian thinking about the Church's doctrines. Whilst challenging the received interpretation by redressing the balance between the Bible and Greek philosophical texts, the essays in the second section of this book nevertheless argue for the philosophical value of early Christian reflections on the notion of divine power. The two groups of thinkers that each of the sections deal with (the Platonic-Pagan and the Christian one) share largely the same intellectual and cultural heritage; they are concerned with the same fundamental questions; and they often engage in more or less public philosophical and theological dialogue, directly influencing one another.

In this paper we investigate composition models of incarnation, according to which Christ is a compound of qualitatively and numerically different constituents. We focus on three-part models, according to which Christ is composed of a divine mind, a human mind, and a human body. We consider four possible relational structures that the three components could form. We argue that a ’hierarchy of natures’ model, in which the human mind and body are united to each other in the normal way, and in which they are jointly related to the divine mind by the relation of coaction, is the most metaphysically plausible model. Finally, we consider the problem of how Christ can be a single person even when his components may be considered persons. We argue that an Aristotelian metaphysics, according to which identity is a matter of function, offers a plausible solution: Christ’s components may acquire a radically new identity through being parts of the whole, which enables them to be reidentified as p

In this paper, we examine Abelard’s model of the incarnation and place it within the wider context of his views in metaphysics and logic. In particular, we consider whether Abelard has the resources to solve the major difficulties faced by the so-called “compositional models” of the incarnation, such as his own. These difficulties include: the requirement to account for Christ’s unity as a single person, despite being composed of two concrete particulars; the requirement to allow that Christ is identical with the pre-existent Son, despite the fact that the pre-existent Son is a (proper) part of the incarnate Christ; and finally the requirement to avoid Nestorianism, i.e., the position that Christ’s proper parts are persons in their own right. We argue that Abelard does have adequate solutions to these problems. In particular, we show that his theories of relations and predication can be put to use in defence of a compositional account of the incarnation.

Do powers have powers? More urgently, do powers need further powers to do what powers do? Stathis Psillos says they do. He finds this a fatal flaw in the nature of pure powers: pure powers have a regressive nature. Their nature is incoherent to us, and they should not be admitted into the ontology. I argue that pure powers do not need further powers; rather, they do what they do because they are powers. I show that at the heart of Psillos’ regress is a metaphysical division he assumes between a pure power to φ and its directedness towards the manifestation of φ-ing, i.e. between a pure power and its essence. But such an ontological division between an entity and its essence has already been shown by Aristotle to be detrimental, condemning the entity to a regressive nature. I show that Psillos’ regress is but an instance of Aristotle’s regress argument on the relation between an entity and its essence. I compare Aristotle’s, Bradley’s, and Psillos’ regresses, showing that Bradley’s and Psillos’ (different) conclusions from the regress arguments lead to impasses. I then build on Aristotle’s directive against regressive natures, arguing with him that an entity is not other than its nature (being divided from its nature by a relation between them). Rather, an entity is an instantiated nature itself. The Aristotelian position I put forward explains how the oneness of the entity is achieved by its being an instance of a type. Thus, the regress is blocked, and the nature of pure powers is shown to pose no threats of an ontological or epistemological kind, if physics gave us reasons to posit pure powers.

This volume is a collection of papers that advance our understanding of the metaphysics of powers — properties such as fragility and electric charge. The metaphysics of powers is a fast developing research field with fundamental questions at the forefront of current research, such as Can there be a world of only powers? What is the manifestation of a power? Are powers and their manifestations related by necessity? What are the prospects for dispositional accounts of causation? The papers focus on questions concerning the metaphysics of powers that cut across any particular subject-specific ontological domain -- whether philosophy of science, philosophy of mind, ethics, epistemology – investigating the metaphysical structure of powers, the nature of the manifestation of powers, the necessity or contingency of a power’s relation to its manifestations, and powers and causation. A number of authors also engage in discussion with Humean and neo-Humean treatments of causation, thereby making contributions to a larger metaphysical debate beyond powers. Additionally, the authors engage critically with the latest contributions to the debate on powers in the literature, thereby bringing together in a wholesome and analytical way the most recent and noteworthy theoretical developments in this research field.
